Find the equation of the graphed line.

Mathematics
1 answer:
Kamila [148]2 years ago
8 0

Answer:

y = -x + 4

Step-by-step explanation:

Mathematically, the equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

from the plot, the y intercept is 4

So we have;

y = mx + 4

To get the value of m, we substitute the coordinates of any point and solve for m

we select the point; (4,0)

so;

0 = m(4) + 4

4m = 0-4

4m = -4

m = -1

so the equation of the line is;

y = -x + 4

{\Huge{\boxed{\mathbb{QUESTION}}}

Write three ratios equal to \frac{4}{36}

{\huge{\boxed{\mathbb{EXPLANATION\:WITH\:REASONING\;}}}

This ratio can be represented as 4:36

Equivalent/Equal ratios<em> - Definition of Equivalent Ratio A ratio can be represented as a fraction. The concept of an equivalent ratio is similar to the concept of equivalent fractions. A ratio that we get either by multiplying or dividing by the same number, other than zero, to the antecedent and the consequent of a ratio is called an equivalent ratio.</em>

Pls help me!! I just need help on both of the following questions, a-d on each
Ymorist [56]
I'll do a and e on the first one to show you how to do it

Then See if you can do the rest

a. 6(-3)<span><span>
</span></span>
When your multiplying or dividing with negative numbers; If one of your numbers is negative like the one above, your answer will be negative

So 6 × 3 = 18 ; but since there is a negative on the 3 your answer will be -18

e. -20 ÷ 5

same for this; 20 ÷ 5 = 4, but since the 20 is negative the answer will be <span>-4

You do b, c, d, and f on the first question. Tell me what you get and we'll go from there

</span>Now for the second question <span>

</span>I will do a and d to show you how to do this then you do the rest<span> (I'm inserting a picture with these)

</span>a. 4(-2 \frac{1}{3}) + 7 \frac{1}{6}
First go ahead and turn the fractions into improper fractions, this makes them a bit easier to work with. When multiplying fractions; they do not need a common denominator, all you do is multiply top by top and bottom by bottom.<span>
However, when you add and subtract fractions you MUST have a common denominator

</span>d. (-4.25)(2) + (-4.25)(-2)
remember from the first problem a negative times a positive gives you a negative<span>

but when you times a negative by a negative you get a positive


Now you try b and c; let me know what you get, and we'll go from there!

Prove the trigonometric identity!<br><br> Please help!! 50 Points!
Rudiy27

Answer:

:)

Step-by-step explanation:

For simplicity I will substitue x for β.

1-sin(2x)=(cosx-sinx)^2\\1-2sin(x)cos(x)=cos^2x-2sin(x)cos(x)+sin^2x\\1=cos^2(x)+sin^2(x)\\1=1

In the first step I used the identity

sin(2x)=2sin(x)cos(x)

And I factored out (cosx-sinx)^2

Then it's just simple algebra to cancel till the 3rd step where we used another identity derived from the Pythagorean Theorem.

cos^2(x)+sin^2(x)=1

That's it!

Next number in sequence 3 -6 12 4 20 ?
Artyom0805 [142]
-6 - 3 = -9
12 - (-6) = 18
4 - 12 = -8
20 - 4 = 16
The first difference is -9. The third difference is -8.
Maybe the fifth difference is -7.
That makes the next term 13.
